Parker 4MSEL2N-316 Compression Male Elbow 1/8-27 Npt

Product Description

The PARKER 4MSEL2N-316 is a stainless steel compression tube male elbow fitting designed to connect tubing to a male NPT threaded port at a 90-degree angle. It accepts a compression-style tube connection on one end and a 1/8-27 NPT male thread on the other, forming a leak-resistant, vibration-tolerant joint without welding or brazing. Rated to 10,300 psi maximum working pressure and capable of handling temperatures from -425 degrees F to 1,200 degrees F, this fitting is suited for high-pressure instrumentation, hydraulic, and process-fluid lines where stainless steel corrosion resistance is required. Licensed plumbers, pipefitters, and instrumentation technicians typically install this fitting in demanding service environments.

This elbow is used in residential and commercial applications where a direction change is needed between a compression tube run and a threaded port on a valve, manifold, gauge, or instrument body. Its broad temperature and pressure range makes it a reliable choice for process instrumentation, pneumatic control lines, chemical service, and cryogenic applications. The 316 stainless steel construction resists corrosion in aggressive media and high-purity systems.

Key Features

• Compression x MNPT end connections allow tool-free tube insertion with a secure ferrule-type seal
• Maximum working pressure of 10,300 psi suits high-pressure instrumentation and hydraulic service
• Extended temperature range of -425 degrees F to 1,200 degrees F covers cryogenic through high-heat applications
• 316 stainless steel construction provides corrosion resistance in chemical, marine, and process environments
• 1/8-27 NPT male thread conforms to standard NPT taper for reliable sealing with PTFE tape or pipe sealant
• Compact elbow geometry routes tubing through tight spaces without bending or kinking the tube

Compatibility

Designed as an OEM-style compression tube male elbow for use with compatible compression tubing and 1/8-27 NPT threaded ports in instrumentation, pneumatic, and process-fluid systems.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or instrumentation technician in accordance with applicable codes such as ASME B31.3 for process piping. Depressurize and isolate the line completely before disconnecting or installing any fitting. Apply an appropriate thread sealant or PTFE tape to the NPT male threads before engagement, and tighten to snug plus the appropriate number of turns per NPT practice — do not overtighten stainless fittings, as galling can occur. Ensure the compression tube end is cut square and fully seated before tightening the compression nut.
